A UNITED STATES PATENT OFFICE ARTHUR IV. KIMBELL, F NEWTON CENTER, MASSACHUSETTS, ASSIGNOR T0 CINCH MANUFACTURING CORPORATION, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLI- N OIS CURTAIN-STICK END Application filed April 9, 1928, Serial No. 268,771. Renewed May 22, 1930.

ming a part of this specification, Figure 1 is an elevation of a portion of a curtain installation showing the use of my invention; Fig. 2 is an edge view of a curtain stick with my improved end portions attached thereto;

0 Fig. 3 is anenlarged end view of a curtain stick end; Fig. 4 is a section taken on the line 44 of Fig. 3; Fig. 5 is a plan view of the curtain stick end shown in Figs. 3 and 4; and Fig. 6 is a plan section taken on the line 6-6 of Figure 1.

The curtain stick end, as an article of manufacture, comprises a one-piece pressed metal v element having a cup-shaped portion preferably having a continuous outer wall 1, the shape of which is governed by the crosssection of the stick to which it is to be attached. In this instance the cup-shaped portion is oval in cross-section. The bottom of the cup is pressed out by suitable die means, to provide a loop 2 extending away from the bottom of the cup. The outer end portion 3 of the loop is preferably curved in crosssection both vertically and horizontally, as

best shown by Figs. 4 and 6.

In the form of my invention illustrated the open end of the cup-shaped portion may be passed over the end of a suitable curtain stick 4 and secured thereto in any suitable .ianner. If the stick is of wood, the wall portion 1 of the cup may be dented inwardly at spaced intervals to provide attaching spurs 5 which are firmly embedded in the stick to hold the end in place, as shown by Fig. 6.

One use of my invention is in connection with curtain installations for vehicles. In such installations, it is desirable to hold the free end of the curtain 6, when drawn, to prevent it from swinging. Suitable cords 7 (or wires) (Fig. 1) are provided at the sides of the window and these pass through the eyes provided by the loops 2. Thus, the end of the curtain 6 is guided in its up and down movements and is held against substantial swinging movement.

The vertically curved surfaces 3 at the ends of the loops 2 provide for a smooth sliding contact with the cord 7 and also prevent wear and tear.

My invention is simple, durable, and inexpensive, and may be quickly and easily applied to the ends of a curtain stick. WVhile a preferred form of the invention has been described above and illustrated by the accompanying drawings, the following claims indicate the scope of my invention.

I claim:

1. A one-piece curtain stick end having a cup-shaped portion open at one end to receive the end of a curtain stick, and a loop extending from the bottom of the cup-shaped portion, said loop having its outer end portion curved vertically and said loop and botat one end to receive the end of a curtain stick, and a loop pressed from material of the bottom of said cup to provide an eye adjacent the bottom of the cup for receiving a guide member, the material of the end portion of said loop being curved in vertical cross-section at its outer end for reducing the surface contact between the loop and the guide member and for providing a smoothly rounded contacting surface to prevent wear and tear of the guide member.

In testimony whereof, I have signed my name to this specification.

ARTHUR W. KIMBELL.
